CNS ADHD/Seizures Flashcards
(17 cards)
What are the non-pharmacological treatments for Attention-Deficit/Hyperactivity Disorder?
Psychotherapy, Behavior management, Family support
Name two pharmacological treatments for Attention-Deficit/Hyperactivity Disorder.
Methylphenidate (Ritalin), Dextroamphetamine (Adderall)
MOA of methylphenidate and dextroamphetamine?
Thought to block reuptake and increases norepinephrine and dopamine at synaptic site to bind to receptors
The exact mechanism is generally unknown.
List some side effects of methylphenidate and dextroamphetamine.
- Nervousness
- Insomnia
- Anorexia
- Tachycardia
- Headache
- Weight loss
What are the adverse effects associated with the use of ADHD medications?
- Aggressive Behavior
- Abuse
- Pancytopenia (low RBC, WBC, and platelets)
What are some causes of seizures?
- Increased intracranial pressure
- CNS infection
- Head trauma
- Withdrawal from barbiturates or alcohol
- Severe hypoxia
- Hypoglycemia
What distinguishes partial seizures from generalized seizures?
Partial seizures impact one side of the brain, while generalized seizures impact both sides.
What is Status Epilepticus?
State of repeated or continuous seizures lasting more than 20 minutes, deemed a medical emergency
What medication is a barbiturate used as an anticonvulsant?
Phenobarbital (Luminal)
controlled substance II, III, IV
What are the side effects of phenobarbital?
- Moderate sedation
- Drowsiness
- Lethargy
- Paradoxical restlessness
- Rash
- Urticaria (hives)
- Nausea & vomiting
- Teratogenic
What is the action of phenytoin (Dilantin)?
Reduces spontaneous electrical impulses in the brain by blocking sodium action potentials
This mechanism is crucial for controlling seizures.
List the side effects of phenytoin.
- CNS: mental confusion, slurred speech
- GI: Gingival hyperplasia
- CV: Severe hypotension & cardiac dysrhythmias (IV)
- Derm: Toxic epidermal necrolysis (TEN), Stevens-Johnson Syndrome (SJS)
- Hemat: Thrombocytopenia, agranulocytosis, pancytopenia
- Teratogenic
Close monitoring is required due to serious potential effects.
What are the nursing considerations for patients taking phenytoin?
- Thorough skin assessment
- Assess BP
- Monitor labs (complete blood count, liver function tests)
- LOC
- Drug blood levels
These considerations help ensure safe and effective treatment.
What is the action of levetiracetam (Keppra)?
Action is unknown; may interfere with sodium, calcium, potassium, or GABA transmission
Its exact mechanism is still under investigation.
What are the side effects of gabapentin?
- CNS: Suicidal thoughts, behavioral changes, dizziness, somnolence, CNS depression, ataxia
- Derm: Drug reaction with Eosinophilia and Systemic Reaction (DRESS)
What are the indications for benzodiazepines like diazepam and lorazepam?
- Status epilepticus
- Treatment of epilepsy
They are often used as first-line agents in emergencies.
What should patients be taught regarding benzodiazepines?
- Take regularly at the same time each day
- Take with meals
- Journal response to medications
- Wear a medical alert tag or ID
- Do not drive until seizure-free for 3 months
- Do NOT discontinue abruptly
